Details
This block will fit 5.7x28mm PS90 Magazines made by FNH. The block fits between the magazine spring and floor plate locking tab and will convert 50 round magazines to hold only 10 rounds. No modifications to your expensive FN PS90 magazines are needed to install. The block can be secured to the spring for a permanent modification.
*The block is no longer marked where to cut for 15 roiund magazines. We now offer a pre-cut block ready to go.
